Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology effective when applied to, for example, a traffic management technique.

[0002]

2. Description of the Related Art For example, the operation status of a route bus operating on a general road is often vague unlike that of a train operating on a dedicated track, and is largely influenced by other traffic conditions and is in accordance with a timetable. Of course, there are many times when you arrive and depart greatly outside of time.

[0003]

In the conventional time search system, the means of transportation which is operated relatively on time and the system which is assumed to be operated on time are mainly used. There is a concern that the deviation from the actual operation situation reflecting the situation etc. may increase, and there is a technical problem that the user cannot know the exact arrival time at the bus stop.

[0004] Further, since the arrival time is displayed on a display or the like provided at the bus stop because it is intended for a user at the bus stop, the user must go to a specific bus stop (or if he is not present). There is also a technical problem that it is not possible to know the expected arrival time of the target bus.

[0005] Furthermore, there is a technical problem that a business operator (bus company) that manages and operates buses cannot know the actual bus operation status and cannot efficiently manage bus schedules. .

SUMMARY OF THE INVENTION An object of the present invention is to provide an operation management technique for a transportation system that allows a user to easily and accurately know the operation status such as the arrival time of an arbitrary transportation system at an arbitrary location.

Another object of the present invention is to provide a transportation operation management technique capable of efficiently performing transportation operation management.

[0008]

According to the present invention, there is provided a mobile communication terminal possessed by a user, wherein the operation status information is collected voluntarily or in response to a request from the user. And outputting to a transportation operation management technique. More specifically, as an example, the operation status of transportation such as a relatively irregular route bus is analyzed,
Allows users to use mobile communications to know if a currently operating bus is operating according to the timetable, and if it is operating late, how long it is operating I do. In other words, the average operating speed, the distance to the next bus stop, the timetable information (bus identification number, operation route, bus stop to stop, estimated arrival time of each bus stop, etc.), the estimated time of arrival at the next bus stop Is calculated, and all the information is notified to the next bus stop. At the notified bus stop, the estimated arrival time of the next bus stop is calculated.
Thus, the bus arrival time is notified to all the bus stops that pass one after another. At each bus stop, the estimated arrival time of the earliest arriving bus is displayed for each route from among the expected arrival times of all received buses. The scheduled arrival time at each bus stop is collected and managed by the center, and by accessing the center from a mobile station such as a mobile communication terminal, the user can extract the scheduled bus arrival time information. According to the present invention, it is possible to predict and calculate the deviation from the fixed time using the moving speed and the position information, and to know the operation status of the transportation means in which the fixed time operation is difficult. By knowing the bus operation status as soon as possible, it is possible to make good use of the low-cost bus transportation system, and by knowing the waiting time, individual users can efficiently use their time. For example, if you can know in advance which bus will arrive at a bus stop that is almost equidistant from your current location, miss a bus that has arrived earlier at one of the bus stops at one of the bus stops Nor. According to the present invention, when you go to the bus stop and there is no bus, despite the same time as the time on the timetable, the bus has already gone and waited for the bus at the next time You can tell immediately if you have to do it or if you can get on the bus right away because the operation is a bit late.
